Liquid flow guide and liquid crystal storage device for liquid crystal coating machine

Abstract

The invention provides a liquid storage device, which comprises a liquid crystal bottle for receiving liquid crystal; the sealing head of a liquid crystal guiding passageway arranged inside the liquid crystal bottle and used for sealing the liquid crystal bottle; and a fluid flow guiding member for guiding liquid crystal introduced to the liquid crystal guiding passageway into the liquid crystal bottle. The fluid flow guiding member is fixedly arranged between the liquid crystal bottle and the sealing head. The liquid crystal introduced into the horizontal hole of the sealing head flows downwards into the liquid crystal bottle without interfering light beams transmitted from the transmission part of a sensor to the receiving part of the sensor. Therefore, when the liquid crystal in the liquid crystal bottle reaches the reference height can be detected. Meanwhile, the liquid crystal is prevented from leaking between the sealing head and the liquid crystal bottle.

Description

technical field [0001] The present invention relates to a liquid crystal coating machine. Background technique [0002] figure 1 It is a side view of a liquid crystal coating machine and a liquid crystal supply device. [0003] like figure 1 Shown, liquid crystal coater comprises: main frame 100; Carriage platform 200, it is arranged on main frame 100; direction (along the Y-axis direction) moving mode is arranged on the main frame 100; Each of them is provided on the coating head unit support frame 300 in such a manner as to move in the width direction of the main frame 100 (along the X-axis direction). [0004] like figure 2 As shown, the coating head unit 400 includes: a support assembly 410, which is movably arranged on the coating head unit support frame 300; a nozzle unit 420, which is arranged at the bottom of the support assembly 410; a liquid crystal bottle holder 430, The liquid crystal bottle holder 430 is arranged on the front of the support assembly 410; ...

AI Technical Summary

Problems solved by technology

This may cause the control unit to incorrectly determine that the liquid crystal has risen to reach the reference height in the liquid crystal bottle 510, even though the liquid crystal has not actually reached

[0026] In addition, liquid crystals flowing downward along the inner surface of the liquid crystal bottle 510 may leak from between the neck of the liquid crystal bottle 510 and the cap 520
